There is provided a resin composition which comprises 100 parts by weight of a saponified ethylene/vinyl acetate copolymer (A) and 0.00001-20 parts by weight of a condensed silicate of lithium aluminium double hydroxide (B) wherein the saponified ethylene/vinyl acetate copolymer (A) has 20-50 mole % ethylene units and has a saponification degree of vinyl acetate unit of at least 96%. The resin composition is excellent in heat stability. The resin composition may contain a thermoplastic resin other than the copolymer (A). The resin composition containing the copolymer (A) and the other thermoplastic resin is excellent in compatibility as well as in heat stability.
